" BRUSH.

To all whom it may concern:

Be it known that I, Orro H. DORSCH, a citizen of the United States, and resident of Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Brushes, of

which the following is a specification.

The present invention relates to improvements in brushes, and particularly a rubber brush for use in the cleaning of bottles, an object of the invention being to provide such a brush which may be operated in a most effective manner, and capable of directing the supply of water so that it will have the greatest cleaning effect. It is also an object to provide such a brush which will clean all portions of the interior of the bottle, and will be comparatively long lived, thereby materially reducing the cost of operation in plants employing such brushes.

With these and other objects in view, my invention is shown in the accompanying drawings and will be hereinafter more fully described with reference thereto, and finally pointed out in the claims.

In the accompanying drawings:

Figure 1 is a front view of my improved brush,

Fig. 2 is an edge view of the same,

Fig. 3 is a top view thereof,

Fig. 4 shows the brush drawn into the guide tube before insertion into the bottle,

Fig. 5 shows the same being inserted into the bottle and engaging the neck portion thereof, and

Fig. 6 shows the brush within the bottle.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings;

Referring to the drawings, and more particularly to Fig. 1 thereof, my improved rubber brush comprises a stem 10 having a passage 11 therethrough, and enlarged slightly at its lower end 12, where it is attached to a screw threaded ferrule 13,

provided on the end of a revolving spindle 14. It is unnecessary to interiorly thread the portion 12 of the brush, as the rubber will conform by reason of its tight engagement to the threads of the ferrule. At the -upper end of the stem there are provided a pair of outwardly extending arms 15 and 16. A reinforcing rib 17 extends along each side of the stem, and is continued along the arms, terminating in pairs of leaves 18 and 19 respectively on each of the arms. The

said leaves arevin the form of halves of spear points. Grooves 20, 21 are provided along the inner face of the arms, continuous with the passage 11.

At each side of the stem there are provided a plurality of fingers 22, preferably three on one side and two on the other inalternating relation. Reinforcing ribs 23 are provided on the rear faces of the fingers at right angles thereto, and of gradually increasing depth from the outer end of the surface of the stem, the same being integral at this point with the stem.

In operation, a plurality of guide tubes 24: are provided, into which the brush may be drawn, and the bottles 25 to be cleaned are moved in inverted position over the tubes. Fig. 4 shows the position of the brush when drawn into the. tube preliminary to the cleaning operation. Itwill be noted, that when the brush is drawn within the tube, the arms 15, 16 are brought into contacting relation, exactly in the" center of the tube, and an unobstructed passage for admission of water is formed by the grooves 20, 21 continuous with the passage 11. WVater is forced through this passage under a pressure of approximately fifteen pounds, and the brush is revolved counter-clockwise at approximately 1500 revolutions per minute. As the brush is moved upwardly in the bottle, the water is continuously in jected therein, and a thorough and forceful cleaning begins at the mouth of the bottle and continues to the bottom thereof. The brush forcefully engages every portion of the neck, and as the bottle gradually widens, the fingers move outwardly into engagement with the sides of the bottle. The brush being about one quarter of an inch wider edges formed by the grooves engage the bottom, and a thorough cleaning takes place, the water being at all times efl'ec-.

tively directed by the grooves, which prevent stopping of the water supply passage.

- with a longitudinal passage therethrough, a

plurality of arms at the end of said stem normally inclined mltwardly from said stem, provided on the inner surfaces thereof with grooves formed continuous with the said passage of the stem, said arms adapted to be pressed into contacting relation, said grooves adapted to maintain an uninterrupted passage continuous with said passage of the stem, and a plurality of relatively long fingers extending outwardly from the sides of said stem.

2. An improved bottle brush comprising an elongated flexible stem portion provided with a longitudinal passage therethrough, a pluralitv of arms at the end of said stem normally inclined outwardly from said stem, provided on the inner surfaces thereof with grooves formed continuous with the said passage of the stem, said arms adapted to be pressed into contacting relation, said grooves adapted to maintain an uninterrupted passage continuous with said passage of the stem, and a plurality of equal length relatively long fingers extending outwardly from the sides of said stem, said fingers being supported at the rear faces by reinforcing ribs, and unsupported at the front faces.

3. An improved bottle brush, comprising an elongated flexible stem portion provided with a longitudinal passage therethrough, a plurality of arms at the end of said stem normally inclined outwardly from said stem, provided on the inner surfaces thereof with grooves formed continuous with the said passage of the stem, said arms adapted to be pressed into contacting relation, said grooves adapted to maintain an uninterrupted passage, continuous with said passage of the stem, outwardly extending leaves at the upper end of said arms, and a plurality of relatively long fingers extending outwardly from the sides of said stem.

4. An improved bottle brush, comprising an elongated flexible stem portion provided with a longitudinal passage therethrough, a plurality of arms at the end of said stem normally inclined outwardly from said stem, provided on. the inner surfaces thereof with grooves formed continiunls with the said passage of the stem, said arms adapted to he 7 sod into contacting relation, said grooves adai ited to maintain an uninterrupted pas sage, continuous with said passage of the stem, and a plurality of equal length relatively long fingers extending out"'*ardly from opposite sides ofsaid stem, the fingers at each side being in the same vertical plane.

5. An improved bottle brush, comprising an elongated ficXible stem portion provic ed with a longitudinal passage therethrough, a plurality of flexible arms at the end of said stem adapted to be moved outwardly by centrifugal force, and a plurality of equal length relatively long fingers extend.- ing outwardly from said stem, said fingers being in the same vertical. plane as said arms.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
